(Just to clarify. I'm using Ooto Melody / Ikuta Erika the 11th right now. If I use Kuroki Erika, I'll likely use her fill name at some point.)

Iku nodded. "Yes, we successors have our own rooms. They are in the highest floor, and from there below. The understudy rooms start in the first (first above the ground) floor. *  However, as mentioned before, one room is a three person room and the other is a four person room. One or two would need to join you."

(* that is not canon. Just making up an explination.)
